Windows General
NOTE: For ease of life when opening either the command prompt, Powershell or Regedit run them as an administrator.
HOWTO: FIX:
Reset Network Adapters via commandline
Open either the command prompt or powershell as administrator, then run the following commands:
netsh winsock reset netsh int ip reset netsh int ipv6 reset netsh advfirewall reset ipconfig /flushdns ipconfig /release ipconfig /renew
Ignore messages about problems with Bluetooth adapters, then reboot the system.
For testing:
ipconfig /release ipconfig /renew arp -d * nbtstat -R nbtstat -RR ipconfig /flushdns ipconfig /registerdns
Exception Breakpoint Has Been Reached
This is an error that is often experienced when shutting down a system. In the case that brought it to our attention was a problem with OneDrive.

Windows Running Slowly
As with most things tech, this fix is not the be all and end all to fix a slow running system, but it is a place to start.
Open a command prompt:
sfc /scannow Dism /Online /Cleanup-Image /ScanHealth Dism /Online /Cleanup-Image /CheckHealth
If DISM reports a fault run the following:
Dism /Online /Cleanup-Image /RestoreHealth
To check for any errors, the log file is located at:
C:\Windows\Logs\CBS\CBS.log
When SFC has completed, run the following:
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt
The text file is outputted to the root of the user's directory.
For further information on deciphering the output, see the Microsoft Knowledge Base article found here.
Error: "Windows Update Cannot Check For Updates"

Batch File to Release TCP/IP, Flush DNS, Reset Winsock, Reset Proxy
Copy and paste the following in to Notepad and save as a batch file:
ipconfig /release ipconfig /renew arp -d * nbtstat -R nbtstat -RR ipconfig /flushdns ipconfig /registerdns
Once you have the batch file run it in a command prompt.
Thanks to The Windows Club.
Windows Apps (Windows 10 & 11)
Open the PowerShell, then run the following:
Method One
Get-Appxpackage –Allusers Get-AppXPackage -allusers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Method Two
Get-AppxPackage -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}
After running the above a system reboot is required.

HOWTO: SHELL MENU:
Add "Take Ownership" to Explorer Right-Click Menu in Win 7, 8 or Vista
Generate File Listing On Shell Menu
Note: The following creates when you right click on a folder an entry in the shell menu called 'Create File Listing'. This creates a text document listing of all the files with in a folder, with the resulting text file saved in the folder itself. The listing is a plain list of all the files, if you want to have listed in the document details of the files themselves i.e. dates, then drop the /b switch.
Open Notepad and paste in the following text:
dir /a /b /-p /o:gen >filelisting.txt
Save the file in to the Windows directory calling it file_listing with a .bat file extension not .txt
Open Windows Explorer, click 'Tools' --> 'Folder Options' click on the 'Files Type' tab, find and highlight 'Folder' then click the 'Advanced' button.
Click the 'New' button, in the 'Action' box paste the following:
Create File Listing
Then browse to and highlight the .bat file created above.
Click all the 'OK' buttons as required.
HOWTO: REMOVE:
Devices & Device Drivers
Printer Server(s)
The Device Manager can be used to remove Print Servers.

DNS cache - Clearing/Flushing (Windows 7/8/10/11)
Even with a web browser's private mode enabled Windows still (inadvertently as this system was in place long before private mode browsing) tracks the websites visited by the machine via the DNS cache.
Output the contents of the DNS cache to a text file (the complete cache may well be too large to display in the terminal):
ipconfig /displaydns > dns.txt
Sample output:
Windows IP Configuration mozilla.org ---------------------------------------- Record Name . . . . . : mozilla.org Record Type . . . . . : 1 Time To Live . . . . : 2 Data Length . . . . . : 4 Section . . . . . . . : Answer A (Host) Record . . . : 63.245.215.20 mozilla.org ---------------------------------------- No records of type AAAA
To clear the DNS cache:
ipconfig /flushdns

Winget
Winget is a package manager available for Windows 10 and installed by default in Windows 11.
winget --help
winget list
NOTE: This will display all the packages that Winget can manage along with their ID reference, which is required if you uninstall via the command line.
winget install <query>
# EG: obs
winget upgrade --all
winget export -o X:\list.json
# Where 'X' is the drive letter of the drive being saved to.
winget import -i X:\list.json
# Where 'X' is the drive letter of the drive being imported from.
OPTIONS: --accept-package-agreements --accept-source-agreements
NOTE: The .json file is saved in plain text so can be edited to suit the system needs.
winget search <query>
# EG: obs
winget uninstall <query>
# EG: 69420
NOTE: Uninstallation is done using the packages ID reference not its name.
NOTE: While the option to uninstall via Winget is available it is safer to use Windows Add/Remove Programs GUI as using the command line may result in dependencies for other installed packages being removed!

HOWTO: ALTER:
Background Intelligent Transfer Service (BITS) - Limiting Bandwidth
After much tarting around we found that the simplest solution to this issue is to purchase a modem/router that can instigate limiting the bandwidth on a system-by-system basis. Windows 11 does provide the ability to limit the speed of Updates, which can cause local area network slowdown.

SupportHours
SupportPhone
SupportURL
- Systems that created from a clean install will not display any values, and will need to be added.
- To do so highlight the OEM key, then right click, select New > String Value and add one of the entries above.
- Rinse and repeat for those you wish to add
- Next double click on the value and in the resulting window add details in the Value data: box
- Click OK
- Rinse and repeat as required
NOTE: The OEM logo should be in .bmp format and no larger the 150x150 pixels, the file path will be needed in the value data.
Once all the information is entered correctly the entire key could be exported for use on other systems.
